Product details
Overview
LS1027ASE7PQA from NXP Semiconductors is a dual-core 64-bit ARM Cortex-A72 system-on-chip (SoC) designed for industrial gateways and TSN-enabled networking edge devices. It operates up to 1.5 GHz, integrates 1 MB ECC-protected L2 cache, supports DDR4/DDR3L memory with ECC, and features four SerDes lanes enabling PCIe 3.0, SATA 3, and multiple 2.5G/1G Ethernet interfaces.
For engineers reviewing the LS1027ASE7PQA datasheet, LS1027ASE7PQA pinout, LS1027ASE7PQA application, or LS1027ASE7PQA equivalent, this page delivers verified SoC-level specifications, validated FC-PBGA-448 pin mapping, confirmed TSN switch and ENETC functionality, and direct alternative options for industrial embedded design continuity.
Technical Context
The LS1027ASE7PQA implements a coherent dual-core Cortex-A72 cluster connected via CCI-400 interconnect operating at up to 400 MHz, with each core featuring 48 KB L1 instruction cache and 32 KB L1 data cache (ECC-protected). The shared 1 MB L2 cache includes ECC support for mission-critical reliability.
Its high-speed I/O subsystem includes two PCIe 3.0 controllers, one SATA 6 Gbit/s controller, and flexible SerDes-based Ethernet interfaces - supporting up to four 2.5G-SGMII ports, one 10G-SXGMII, and integrated TSN-capable Ethernet Switch and ENETC with IEEE 1588/1722 support for deterministic networking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core ARM-based networking SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS1043ASE7Q1A | Quad-core Cortex-A53 @ 1.7 GHz, no Cortex-A72; adds SEC 4.0 crypto engine but lacks TSN switch. | Better raw throughput for firewall/NAT, but no hardware TSN scheduling or IEEE 1588 hardware timestamping. | Select when prioritizing cryptographic throughput over deterministic networking - not suitable for time-critical motion control. |
| IMX8MPLUS | Quad-core Cortex-A53 + Cortex-M7, no SerDes; uses external PHYs for Gigabit Ethernet, no PCIe/SATA native support. | Strong multimedia and AI inference capability, but requires additional chips for industrial networking features. | Select for HMI+control convergence where video processing dominates; avoid when needing integrated PCIe/SATA/TSN. |
Compared with LS1043ASE7Q1A and IMX8MPLUS, LS1027ASE7PQA uniquely combines Cortex-A72 performance, hardware TSN switching, and SerDes-based multi-protocol I/O in a single die - making it the only option among the three that satisfies both high-throughput routing and sub-microsecond deterministic networking requirements.

FAQ
What is the maximum operating frequency of the LS1027ASE7PQA?
The LS1027ASE7PQA operates at up to 1.5 GHz across both ARM Cortex-A72 cores. This frequency is sustained under thermal and voltage conditions specified in the recommended operating conditions table (Section 3.1.2) of the official NXP datasheet Rev. 0 (December 2019), with derating applied above 85°C ambient.
Does the LS1027ASE7PQA support DDR4 memory with ECC?
Yes, the LS1027ASE7PQA includes a 32-bit DDR3L/DDR4 memory controller with full ECC support for both single-bit error correction and double-bit error detection. ECC functionality is implemented in hardware and enabled via register configuration in the DDR controller module - required for use in safety-certified industrial applications.
How many Ethernet interfaces does the LS1027ASE7PQA support natively?
The LS1027ASE7PQA supports up to five distinct Ethernet interfaces: one RGMII port, one 1G/2.5G SerDes-based ENETC interface, and up to four 2.5G-SGMII ports via its SerDes lanes. All interfaces are TSN-capable, with hardware timestamping and scheduling logic embedded in the switch and ENETC blocks.
Is the LS1027ASE7PQA pin-compatible with other LS102xA family members?
No, the LS1027ASE7PQA is not pin-compatible with LS1021A or LS1026A variants. While all share the FC-PBGA-448 package footprint, ball assignments differ significantly - especially for DDR, SerDes, and peripheral signals - requiring unique PCB layout per variant per NXP's pinout documentation.
What security features are integrated into the LS1027ASE7PQA?
The LS1027ASE7PQA integrates Arm TrustZone for hardware-enforced secure world isolation, a dedicated Security Engine supporting AES-128/256, SHA-256, RSA-2048, and ECC, plus immutable Secure Boot with hash-based image authentication. These features are active upon power-on reset and require no external security IC to establish a root of trust.
